Abstract
Stakeholder expectations, regulatory standards, and investor demands call for solid actions to reduce greenhouse gas (GHG) emissions in mineral and metal production. With ambitious 2030 and 2050 decarbonization targets, the mining sector is transforming operations and adopting new technologies to reduce its carbon footprint. Among those technologies, most mining companies are planning to accelerate site electrification. Therefore, in British Columbia (BC), where 25 mines are operational and 21 exploration projects rank among NRCan’s top 100, access to reliable, low-carbon electrical power is essential. However, transmission and distribution infrastructure constraints in BC are just as critical as installed low-carbon generation capacity to meet the demand considering the industry’s 2030 and 2050 targets.
Foresight Canada’s current BC-wide study projects that clean electrical power demand of mine electrification will require a power generation increase of 18% and 24% by 2030 under low- and high-electrification scenarios, respectively. This need rises to 20% and 35% by 2035 for the same scenarios. With broader electrification trends, including battery electric vehicle (BEV) adoption among households and rising demand in sectors like oil and gas (up by an estimated 2 to 7 GW by 2030), reliable electrical power access poses a significant challenge for miners in BC.
This study assesses whether BC’s grid is equipped to support these electrification needs and highlights the challenges and risks mining companies face under various electrification scenarios. Our analysis examines current and forecasted power supply, transmission, and distribution infrastructure, as well as regional bottlenecks that could constrain sector-wide electrification in BC. We also address cost implications, competition for limited power, and non-monetary risks, including GHG emissions targets for BC’s mining companies.
In addition to identifying these limitations and risks, the presentation outlines potential mitigation strategies for cost-effective and timely decarbonization in the BC mining sector. Recommendations include on-site technological solutions, innovative design options, and collaborative approaches involving alternative financial and cost mitigation measures. This includes exploring industrial partnerships, infrastructure consortiums, and engagement with Indigenous communities to strengthen BC’s mining sector’s readiness for electrification.
